UNITED STATES PATENT OFFICE WILLIAM E. PINKLNEY, or scAnBno,

WEST VIRGINIA.

MINERS LAMP.

Specification of Letters Patent. Application filed March 7,

To all whom it may concern Be it known that I, WILLIAM E. PINKNEY, a citizen of the United States, residing at Scarbro, in the county of Fayette and State of West Virginia, have invented certain new and useful Improvements in Miners of which the following is a specification.

This invention relates or torches and has for its object the provision of a comparatively simple and thoroughly eificient device of this character, the construction of which is such as to prevent lateral rocking or oscillation of the torch when positioned on the cap of the wearer.

A further object is to provide a lamp or torch having a inclined front wall so that the lamp or torch may be placed on the ground or other support and moved from place to place without danger of the wick tube overbalancing the body of the torch and upset-ting the latter when the oil in the lamp is consumed or partially consumed.

A further object is to form one of the side walls of the lamp with a depending lip adapted to yieldably engage the pivoted lid or cover when the latter is moved to closed position and thus prevent said lid from swinging open and spilling the oil in the reservoir.

A still further object of the invention is.

generally to improve this class of devices so as to increase their utility, durability and efiicienoy, as well as to reduce the cost of manufacture.

Further objects and advantages will appear in the following description, it being understood that various changes in form, proportions and minor details of construc tion may be resorted to within the scope of the appended claims.

For a full understanding of the invention and the merits thereof and also to acquire a knowledge of the details of construction and the means for efi'ecting the result, reference is to be had to the following description and accompanying drawings, in which:

Figure l is a perspective view of a miners lamp or torch constructed in accordance with my invention, showing the same in position on a cap; Fig. 2 is a vertical sectional view of the same; Fig. 3 is a transverse sectional view taken on the line 3-3 of Fig. 2; Fig. 4

to miners lamps.

positively fiat bottom and a rearwardly is a transverse sectional view taken on the line 4: 4: of Fig. 2; Fig. 5 is a detail vertical sectional view showing the construction of the locking lip for the lid or cover.

Corresponding and like parts are referred to in the following description and indicatedin all the views of the drawings by the same reference characters.

The improved miners lamp or torch forming the subject matter of the present invention comprises a body portion of substantiallyrectangular cross sectional formation and formed of brass, tin, copper or other suitable material, said body portion having a flat bottom 5 and a flat vertically disposed rear wall 6 adapted to bear against the cap 7 and prevent lateral rocking or oscillation of the lamp when in position thereon.

The front wall 8 of the lamp is inclined rearwardly from the bottom thereof to the top of the lamp so that when the oil in the reservoir 9 is consumed or partially consumed, the weight of the wick tube 10 will not overbalance the body portion and cause the latter to upset when placed on the ground or other suitable support.

The body portion is provided with an opening 11 through which oil or illuminant is introduced into the reservoir 9, there being a shoulder 12 formed in the walls of the lamp and defining a vertically disposed flange 13 entirely surrounding the opening 11, as shown. One of the side walls of the body port-ion is extended laterally at the flange 18 to form a transversely disposed eye 14, the metal forming the eye 14 being thence extended inwardly and downwardly in spaced relation to the flange 13 to form a spring lip 15 adapted to engage the cover 16 when the latter is moved to closed position. The cover 16 is provided with a depending enlargement 17 preferably of the same height as the flange 13 and which fits within the opening 11, as best shown in Fig. 3 of the drawings.

The metal forming the top of the cover or lid 16 is extended longitudinally and bent upon itself to produce an eye 18, similar in construction to the eye 14, there being a wire loop 19 extended through the eyes 141 and 18 to form the hinge of the cover. Thus it will be seen that when the cover 16 is moved to closed position, the enlargement 17 will bear against the spring lip 15 and depress the latter so as to cause the lip to yieldably engage the enlargement 17, and thus prevent accidental opening movement of the cover. It will also be noted that when the lip 15'is forced in the direction of the flange 13' by engagement with the enlargement 17 of the cover, the metal constituting the eye M will grip the hinge or loop l9 and assist in preventing accidental opening movement of the cover.

By reference to Figs. 3 and 4 of the drawings it will be seen that the side walls 20 of the lamp or torch are inclined in the direction of the opening 11, such a construction forming oppositely disposed flat bearing surfaces so as to permit the miner to readily grasp the lampor torch when positioning said lamp on or removing the lamp from the cap 7. The bottom of the lamp being perfectly flat and the front wall thereof inclined rearwardly, the lamp may be readily placed on a ledge or other suitable sup port while the miner is at work without danger of being upset, as before stated.

Any suitable means may be employed for retaining the lamp or torch in position on the cap 7, and by way of illustration, a hook 21 is shown attached to the flat rear walls 6 of the lamp for engagement with a socket onthe cap 7.

It will here be noted that the lid or cover is retained in position on the body of the lamp without the employment of solder, thus preventing the heat from.the lamp or torch from affecting said cover, which is the case with miners lamps now in general use.

The device is extremely simple in construction and may be manufactured and placed on the market at a small cost.

Having thus described the invention, what is claimed as new is:

1. A miners lamp comprising a body portion having an opening, the top of the body' portion being provided with an upstanding flange surrounding said opening, the metal forming the flange being bent laterally to produce an eye and thence extended inwardly and downwardly in spaced relation to the inner face of the flange to form a spring lip, a cover having a corresponding eye, a loop extending through said eyes and forming the hinge of the cover, said cover being adapted to engage and depress the spring lip when the cover is moved to closed position.

2. A miners lamp comprising a body portion having an opening formed in the top thereof, the upper portion of the lamp being provided with an upstanding flange surrounding the opening, the metal constituting the flange being projected laterally beyond said flange and bent upon itself to form an eye and thence extended downwardly within the opening and in spaced relation to the inner face of the flange to form a depending spring lip, a cover having a depending enlargement and provided with an eye, a loop extending through said eyes and forming the pivotal axis of the cover, the enlargement on the cover being adapted to engage and depress the spring lip when the cover is moved to closed position.

In testimony whereof I afiix my signature in presence of two witnesses.
